Application filed October 20. 1905- Serial No. 283,591.

To all whom it may concern.-

Be it known that I, GEORGE R. MOON, a citizen of the United States,residing at Cleveland, in the county of Cuyahoga and State of Ohio, haveinvented certain new and useful Improvements in Ovens, of which thefollowing is a specification.

My invention relates to new and useful improvements in ovens.

The object of the invention is to provide within the oven a spreading ordeflecting drum into which air is admit-ted from the exterior of thecasing. This drum serves two purposes-that of supplying air to theurners for properly supporting combustion and preventing overheating ofthe lower part of the heating-compartment.

Still another feature resides in the arran ernent and construction ofthe parts where y the distribution of the heat products is equalized andthe said products fully deprived of their heat before escaping from theoven.

Finally, the object of the invention is to provide a device of thecharacter described that will be strong, durable, and eflicient andsimple and comparatively'inexpensive to produce.

With the above and other objects in view the invention consists of thenovel details of construction and operation, a preferable embodiment ofwhich is described in the specification and illustrated in theaccompanying drawings, wherein- Figure 1 is a lon itudinal verticalsectional view taken on the line a: w of Fig. .2. Fig. 2 is a transversevertical sectional view taken on the line '31 y of Fig. 1. Fig. 3 is ahorizontal cross-sectional view taken on the line aa of Fig. 1, and Fi 4is a transverse vertical sectional view talien on the line b b of Fig.1.

In the drawings, the numeral 1 designates the casing of the oven, whichis substantially rectangular in cross-section and constructed of anysuitable sheet metal. At the central portion of its to i an outlet orescape opening 2 is provided. home distance above the bottom of the ovenan air-drum 3, trian uler in crossseotion, is arranged, extendingongitudinall; of the oven between the end walls thereof. The drum issecure-Iv fixed in place and at each end is provided with airinlvtl'rl'lcnings 4, which communicate and register with air-openings 5,formed in the end walls. The apex of the drum, which isdirern-ddownward, is |')'l'ovidv(l with a plurality of mfwnlllgs 0, throughwhich the mr admiIu-d by the openings 4 and 5 is ejected. Slightly belowthe drum and on each side of the apex thereof parallel gas-burners 7 areprovided. By provision of the air-drum 3 a sufiicient quantity of air issupplied to the burners to properly support combustion, while at thesame time the upwardly-inclined sides of the drum act to spread ordeflect the heat products from the burners, so as to cause an equal distribution of the same, as will be hereinafter described. The upper sideof the drum 3, which is fiat, supports and forms the bottom of aheating-compartment A, at the front of which the oven is provided withan openin 8, covered b r a suitable door or closure 9. he sides of t ecompartment A are formed by vertical side or end plates 10, which extendentirely from thefront to the back of the oven and are covered by a toplate 11, extending in a like manner. The ack of the com artment isformed by a vertical plate or we 12, which extends upwardly from thedrum 3, but terminates short of the under side of the top plate 11, soas to provide an inlet-opening 13. The compartment A is divided into twocells by means of a shelf or horizontal plate 14, which terminates shortof the front wall of the oven, so as to rovide communication between thetwo cel s. Outlet-o enings 15 and 16 are provided in the end Wa s 10 ofthe compartment, the openings 15 being positioned near the forward endof the upper cell and the openings 16 arranged near the rear end of thelower cell. These openings provide for the escape of the products fromthe cells after the some have assed there thron -h. The end or side wals 10 provide with are end or side walls of the oven-casing verticallines B, which terminate at their u per end in a horizontal flue orchamber formed by the top plate 11 and the top oi the oven-casing, whilethe wall or plate 12 of the compartment A forms with the rear or backwall of the oven-casing a vertical heat-conducting line D, said fluebeing closed at its upper end by the plate 11, but havingcommul'licntion through the opening 13 with the up no cell of thecompartment.

deferring to Fig. 2, it will be obvious that the heat prmlucts generatedby the righthund humor 7 will be directed by the drum 3 lulu lluverticalhml-l-romlurting llnc l). ,up which they will puss through the opening13 into the upper cell of the mnnpnrtnwm. A, while the heal productsgenerated by the burner 7 on the left-hum! side of the drum will beduller-ted and directed by tho some as to pass up into the lower cell oft-hc com- )artment A, circulating therein and fully eating the same. Theheat products passing to the rear of the lower cell will escaple throu hthe opening 16 into the side Hues (see Figs. 1 and 2,) while theproducts at the forward end of the said lower cell will pass up aroundthe 'frontedge of the shelf 14 into the upper oell,wherc the)willcirculote and mingle with the roducts entering through the opening13, al the products finally passing out through the openings 15 into thevertlcul flues B,where mixing with the products from the openings 16they will ass upward Into the horizontal fiue (J and nail escape throughthe opening 2.-

It will be apparent that by dehverm a greater amount of heat to theupper col of the compartment and by provision of the cold-air drum 3 atthe bottom of the lower cell the compartments are equally heated and theheatso regulated that one cell receives comparatively the same amount asthe other.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is-

1. An oven comprising an outer casing, a drum extending from end to endof said easingand having ontlet-openin s at the bottom thereof,gas-burners arranged upon each side of said outlet-openings, and aboking-chumher located above said drum, the interior of said drum beingin communication with the ntmospllllere.

oven comprising an outer casing, a drum extending from end to end ofsaid casing, said drum beinq triangular in cross-section and forminginclined side walls, the interior of said drum being in communicationwith the atmosphere and with the interior of the outer casing throughopenings formed at the lower so '5 portion of said drum, gas-burnersarrz'inged adjacent said drum upon each side of said o )enings, and abakingchamber located a IOVt' said drum.

3. Au oven comprising an outer casing. a. drum extending lengthwise ofsaid casing, the interior of said drum being in comn'iunication with theatmosphere and said drum having air-outlet. openings at its bottom,gas-burners arranged adjacent said outlet-openings, a baking-chamberlocated above said drum, means for conducting the heat from one of saidgas-burners to the upper portion of the baking-chamber, means forconducting the heat from the other of said gas-burners to the lowerportion of the baking-chamber, and means for permit ting the passage ofheat from the upper and lower portions of the bakingchomber to theinterior of the. outer easing.

4. An oven eomprisin an outer casing,

artitions located in said outer casing and Forming a bakingrhamber, saidpartitions comprising two sidewalls, a top wall and a rear wall whichterminates short of the top wall, a deflectingdmm which forms the bottomof the oven, the interior of said drum being in communication with theatmosphereond said drum having oiroutlet openings in its lower portion,burners arranged u 101] each side of sold outlet-openings and saideflectlug-drum being ndated to direct the products of combustion iiomone of said burners to a passage formed between the rear wall of thebakin -chamber and the outer casing and to direct 51c products ofcombustion from the other of said burners to the lower portion of thebaking-chamber.

In testimony whereof I aliix my signature in presence of two witnesses.
